M24128-BFDW6TP [STMicroelectronics]

The M24128 is a 128-Kbit I2C-compatible EEPROM (electrically erasable programmable memory) organized as 16 K × 8 bits.

The M24128-BW can operate with a supply voltage from 2.5 V to 5.5 V, the M24128-BR with a supply voltage from 1.8 V to 5.5 V, and M24128-BF and M24128-DF with a supply voltage from 1.7 V to 5.5 V. M24128-BF and M24128-DF can also operate down to 1.6 V, under some restricting conditions. All devices operate with a clock frequency of 1 MHz (or less), over an ambient temperature range of -40 °C to +85 °C.

The M24128-D offers an additional page, named the identification page (64 bytes). It can be used to store sensitive application parameters, which can later be permanently locked in read-only mode.
